 * Hello everybody, I got a question concerning the $query_string variable.
 * What I want to do is: i want to exclude one category from all of my archive pages.
   According to the [Codex](http://codex.wordpress.org/Template_Tags/query_posts#Usage)
   I just have to make a function call like this in my archive.php:
 * `query_posts($query_string . &cat=-3);`
 * This works to some degree: category 3 is excluded but the loop now always shows
   the same entries, no matter which category I am browsing to. I guess this is 
   because $query_string is always empty (tested it with an echo statement on several
   pages/posts).
 * Do I need to call a global first to make this work? Or is this not supposed to
   work that way? Would be glad if you could help me. Thanks
